Connection Guide
This adapter supports four primary wiring configurations:
- Pins 4 & 5: Insert wire A into Pin 4 (485A) and wire B into Pin 5 (485B). If inverted, A connects to 485B and B to 485A.
- Pins 5 & 6: Insert wire A into Pin 5 (top input) and wire B into Pin 6.
- Pins 6 & 7: Insert wire A into Pin 6 (485A) and wire B into Pin 7 (485B). Swapping positions reverses the A/B assignment.
- Pins 7 & 8: Insert wire A into Pin 7 (top) and wire B into Pin 8 (top).

Frequently Asked Questions
Q: What is the RJ45 to RS485 converter adapter used for?
A: This RJ45 to RS485 converter adapter allows you to connect RS485-protocol devices — such as industrial sensors, surveillance cameras, or access control panels — to systems using an RJ45 interface. It translates the RS485 differential signal into a standard RJ45 connection for easy integration into larger monitoring or automation networks.
Q: Which pin pairs are supported by this RS485 to RJ45 terminal adapter?
A: The adapter supports three pin pair configurations: pins 4/5, pins 6/7, and pins 7/8. This flexibility ensures compatibility with the majority of RS485 devices that route their A/B signal lines through an RJ45 port.
Q: Is this adapter suitable for outdoor or industrial environments?
A: Yes. With an operating temperature range of -40°C to +85°C, this RJ45 to RS485 converter is built to handle both extreme cold and high-heat industrial environments, making it suitable for outdoor monitoring installations and factory automation systems.
Q: Do I need any additional tools or software to use this adapter?
A: No additional software is required. Simply insert the RS485 signal wires (A and B) into the correct terminal block positions as per your device's pinout, then plug the RJ45 connector into your device. The adapter works as a passive hardware interface — no drivers or configuration needed.
